Audio data search control device

Abstract

In a multi-session disk, a microcomputer of an audio data search control apparatus judges whether or not a search operation for a last audio data file in an optional session during the search operation in the session (Step S 11 ), forcibly moves an optical pickup 11 during a required forcible-movement time length T along a radial direction of the multi-session disk when it is judged that the search operation is completed (Steps S 12 and S 13 ), and restarts the search operation in a next session of a different format after the forcible movement is completed (Steps S 14 -S 16 ).
